THat Naxcel is awesome. I had to use it on a mustang mare I use to have I only had her for about 4-5months and several of those months she was so sick with pneumonia but when I first got her we bonded and I was riding her within two weeks and was riding her outside of a arena within a month. Then she got real bad sick and it went down hill from there. BUt I kept a journal about it and I was giving her breathing treatments, hanging IV fluids in that little 12x12 stall, she got shots everyday........but she was always happy to see me.......
I ended up taking her to the University of Tennessee and the pneumonia had scarred her lungs so bad she could not hold her O2 saturation up over 56% so I knew when she nudged me it was time to let her go and I did and I brought her and she is on the hill with the other two great loves in my life.........
Oops sorry I got off on a long story, I just meant to say I have used that drug and several others where pnuemonia is concerned even people drugs that were prescribed by the vet in the horses name and you go to the pharmacy and pick it up, and they are awesome..............
I hope Sunny gets better soon.........
